Two models.Radius NX 4×4 (4 analog inputs, 4 analog outputs) and Radius NX 12×8 (12 analog inputs, 8 analog outputs). Both feature 64×64 redundant Dante and identical DSP resources. The two differ only in analog I/O, logic output, and external control input capacity. The reduced cost of the 4×4 makes it extremely competitive in applications where many Dante endpoints are routed to a primary DSP and fewer analog connections are required.

Optional virtualized and scalable AEC coprocessor module. For conferencing applications the dual-core coprocessor provides up to 16 channels of full bandwidth AEC with unparalleled clarity and intelligibility.

128×128 Super Matrix. A Next-generation SHARC Dual-core Processor enables a Composer Super Matrix – placing the burden of large matrices in one core while freeing the second core for general purpose signal processing – making it possible to design very large and complex systems around a single Radius NX. View modes make navigating through large matrices a breeze.

Configurable4-port gigabit switch. Services both Dante and control networks, eliminating or reducing the need for external switches while avoiding 100 Mbit bottlenecks.

An internal DSP coprocessor module may be installed for additional application-specific processing such as acoustic echo cancellation (AEC).

A USB 2.0 audio I/O port with class 1.0 legacy modes on a high-retention Type B connection is configurable for up to 8×8 line I/O as well as 2×2 line I/O, 1×1 speakerphone, or 1×1 echo- cancelling speakerphone profiles.

The front panel shall include a display and a momentary switch. The display shall provide communications and system status, I/O metering, and fault messages.

External control shall include dedicated software screens as well as preset selection, I/O level control and muting using the optional ARC wall panel remote controls via industry-standard CAT5 cable with RJ45 connectors. A built-in web server shall provide four instances of ARC-WEB, which allows for user control from nearly any web browser or mobile device. Logic I/O shall consist of four contact closures or two potentiometer inputs along with four logic outputs. The logic outputs may be used to drive LEDs directly or control external relays or switchers. All program memory shall be non-volatile and provide program security should power fail. The device shall provide an on board real time clock to facilitate automatic, timed changing of presets and may sync to NTP. Third-party control systems may interface over IP and RS-232 using a published ASCII control protocol.

The device shall have an IEC power input socket for 120-240 VAC. The device shall meet UL/ CSA and CE safety requirements and comply with CE and FCC Part 15 emissions limits. The device shall be RoHS compliant. The chassis shall be constructed of Galvalume and molded plastic, and mount into a standard 19” 1U EIA rack using detachable rack ears. The device shall be a Symetrix Radius NX 4×4.

Early to the Party. In 2007 Symetrix recognized the need for a standardized, high performance digital audio networking protocol – not only for our own products but for the pro audio industry at large. After considerable research, we aligned with Audinate to become one of the earliest licensees of the Dante protocol. The choice has proven prescient. Legacy protocols like Cobranet have faded into obscurity. Newer protocols, AVB for example, have failed to gain traction due to inherent technical drawbacks. With hundreds of third party licensees and a list of commercially available products that is growing exponentially, Audinate’s Dante protocol is now an established standard – far and above any competition.

Since the introduction of our first Dante enabled product in 2012, we’ve leveraged the benefits of the protocol for our own box-to-box audio networking, as well as for peer-to-peer connection with major third parties including Yamaha, Shure, and AudioTechnica. In countless case studies, designers have used off-the-shelf switches and cabling to link Symetrix DSPs to Dante-enabled mixing consoles, microphones, power amplifiers, loudspeakers, and laptop computers.

Dante is in our DNA … and that has placed us in a highly advantageous position. While our competitors choose to design for and support multiple network audio protocols, in some cases proprietary, Symetrix designs for and supports only one ubiquitous and clearly accepted industry standard: Audinate’s Dante.

Economical and Versatile. Dante does away with heavy, expensive analog cabling, replacing it with low-cost, readily available CAT5e, CAT6, or fiber optic cables. Using Dante’s logical routes instead of physical point-to-point connections, a network can be expanded and reconfigured at any time.

Outstanding Audio Performance. Using the Dante protocol, Symetrix transmits and receives uncompressed full bandwidth audio with up to 32 bits of resolution at a 48kHz sample rate. Audio is transmitted and received digitally eliminating the analog challenges of interference from other electrical equipment, crosstalk between cables, or signal degradation over long cable runs.

Unicast or Multicast. Dante channels can be configured as either unicast or multicast making the best use of available bandwidth. Unicast provides direct point-to-point connections; multicast streams audio to multiple destinations simultaneously.

Ease of Programming. Composer is used to program Symetrix Dante equipped DSPs and analog I/O expanders. In addition to the programming of Symetrix devices, Composer also natively configures the setup and routing of select third-party Dante endpoints. Integrators can design a complete end-to-end DSP signal path using just one application.

The Symetrix Dante Advantage. We provide our customers with a network audio solution that is flexible, dependable, scalable, and supportable. In short, just what you’d expect from an industry standard … and just what you’d expect from Symetrix.
